I have a branch with the SCD30 working with Environmental and AirQuality by sharing access to the Sensor object here. It's based on an older firmware version, and I think we also have a branch for the RAK but I cannot recall if there were any changes outside of variants/* for the RAK4631. I've had a Pico with an older version of this branch running for two weeks(?) now in my lab with no hiccups so far.

edit: I can submit a PR if people want, but I also know there's several large refactors happening at the moment which is why we based off of 4c97351 which I think is v2.5.20.4c97351
